Ingredients
Pastry Shells
- 2 1/2 cups all-purpose flour
- 1/2 teaspoon salt
- 1 cup cold unsalted butter, cubed
- 1/4 cup granulated sugar
- 1/4 cup ice water
Tart Filling
- 3/4 cup butter
- 1 1/2 cups granulated sugar
- 6 large egg yolks
- 1/4 cup all-purpose flour
- 1/4 cup heavy cream
- 1/4 cup whole milk
- 1 teaspoon vanilla extract
- 1 tablespoon lemon juice
- 1 teaspoon ground cinnamon
Instructions
1. Make the Pastry Dough
In a large bowl, combine the flour and salt. Cut in the cold butter until the mixture becomes crumbly with small butter pieces remaining.
Add the sugar and ice water, mixing just until the dough comes together.
Shape into a disc, wrap tightly, and refrigerate for at least 1 hour.
2. Prepare the Tart Shells
Preheat the oven to 400°F (200°C).
Roll out the chilled dough on a lightly floured surface. Cut circles large enough to fit into a greased muffin tin.
Press the dough into each muffin cup and chill for another 15–20 minutes.
3. Blind Bake the Shells
Bake the pastry shells for 12–15 minutes until lightly golden.
Remove from the oven and set aside while preparing the filling.
4. Make the Custard Filling
In a saucepan over medium heat, melt the butter.
Whisk in the sugar, egg yolks, flour, heavy cream, milk, vanilla extract, lemon juice, and cinnamon until smooth and fully combined.
Cook gently for a few minutes until slightly thickened.
5. Fill and Bake
Pour the filling into the prepared pastry shells, filling each about 3/4 full.
Bake for 18–22 minutes or until the tops develop deep golden brown caramelized spots.
6. Cool Slightly
Allow the tarts to cool in the pan for 10 minutes before transferring to a wire rack.
Serve warm or at room temperature.

Tips for Bakery-Style Portuguese Tarts
For the flakiest pastry, keep the butter cold throughout the dough-making process. Small pockets of butter create those delicate crisp layers during baking.
Baking at a high temperature is also essential for developing the signature caramelized top while keeping the custard smooth and creamy inside.
